7 Claims. (Cl. 30-283) This invention relates to a tool to skive leatherand similar materials.

An object of the present invention is to provide a skiving toolembodying novel blade-mounting means enabling quick, safe and easyattachment to or removal of a blade.

Another object of the invention is to provide a skiving tool in whichthe blade is held under resilient flexure to conform it to the supportframe over which it is so held.

A further object of the invention is to provide, in a skiving tool,adjustable gauge means to enable variation in the depth and/ or angle ofthe skiving cut of the blade of said tool.

The invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in a workingposition and easily disconnected therefrom, economical of manufacture,relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully appear inthe course of the following description. However, the drawing merelyshows and the following description merely describes one embodiment ofthe present invention, which is given by way of illustration or exampleonly.

In the drawing, like reference characters designate similar parts in theseveral views.

Fig. 1 is a front elevational view of a skiving tool according to thepresent invention.

Fig. 2 is a side elevational view thereof with the handle broken away.

Fig. 3 is an end view of the tool as in Fig. 2.

Fig. 4 is a longitudinal sectional view as taken on line 4-4 of Fig. 1.

The skiving tool that is illustrated comprises, generally, a handle 5, asupport plate 6 across one end of the handle and against which a blade 7is adapted to be pressed, resilient means 8 to engage the ends of saidblade to resiliently press the latter against support plate 6, and agauge 9 adjustably carried by the handle and operatively associated withan end of the support plate to vary the depth and/or angle of theskiving cut performed by the tool.

The handle is formed of a length of preferably squaresectioned rod bentat one end 10 to form sides 11 which are spread apart at the endopposite to end 10 and are somewhat closer together adjacent the latterend to accommodate the hand. At their free ends, sides 11 are angularlybent as at 12 out of the general plane of the handle.

The support plate 6 spans between side ends 12 and is permanentlyconnected at its ends to said ends 12. As shown particularly in Fig. 3,plate 6 is transversely convexly bowed and is formed with a bend 13 toforwardly offset its blade-supporting portion 14 with respect to portion15 thereof. An elongated opening 16 extends across the plate 6 and is solocated that one portion thereof is formed in portion 14 and the otherin portion 15. Because of the transverse bow in plate 6 and the bend 13therein, the portions 14 and 15 are quite inflexnited States Patent 02,735,180 Patented Feb. 21, 1956 ible although only the ends of theformer portion are connected to handle ends 12, as shown in Fig. 2,wherein it is seen how the main portion of the handle extends angularlyaway from said portion 15. Along its upper edge, plate portion 14 isprovided with stop blocks 17 that serve as position-limiting abutmentsfor blade 7. Said blocks are located with respect to slot 16 and bend 13according to the width of blade 7 to bring the cutting edge 18 thereofslightly above said bend when said blade is located with the oppositeedge 19 against said blocks.

The blade 7 preferably comprises an elongated member of rectangularform, the one shown being the blade used in the Schick repeating razor.Since such blade can be obtained in the open market, the same is,therefore, quite inexpensive as compared to specially made blades.

The resilient means 8 is carried by each handle side 11 and, except forbeing oppositely formed on each side, is the same on both sides. Eachsaid means comprises a generally C-shaped clip member 20 fitting overeach end 12 and of suflicient front-to-back depth to slide laterallyrelative to said ends, as shown more clearly in Figs. 2 and 3. Eachmember 20 has a side wall 21 that connects a front wall 22 and a backwall 23. A guide wall 24 extends from wall 23 parallel to wall 21 and ina direction toward wall 22. Walls 21 and 24 are spaced to slidingly fitover end 12, while walls 22 and 23 are spaced to allow for the mentionedsliding movement of member 20.

A resilient arm 25 fixedly extends from each wall 24 and is connected toeach respective handle side 11 as by an end 26 thereof extending into ahole provided in each said side 11. Thus, each member 20 is carried onthe free end of arm 25 and the latter constitutes a spring means that isnormally biased or tensioned in a direction to cause wall 22 of saidmember to resiliently press against plate portion 14 where the latter isconnected to handle ends 12.

From the foregoing it will be clear that the walls 22 normally press theends of blade 7 to flex the latter over the curvature of plate portion14 in the manner shown, and that, by pressing walls 23 of members 20forwardly or to the left, as shown in Fig. 2, the blade is released forreplacement.

The gauge 9 is adapted to be removably attached to either handle side11, as desired, thereby enabling tilting of the tool to proper positionby both rightand lefthanded users. As shown, said gauge comprises amember 27 held in general alignment with one or the other handle side 11by a spring clip 28 that frictionally and slidably engages the side 11to which applied.

The upper end 29 of member 27 is forwardly offset so as to be forward ofplate portion 15 and so that one of several notches 30, formed in saidend 29, is engaged with the lower edge 31 of portion 15. Since gauge 9can be slid along side 11, end 29 of member 27 can be adjusted tovarious amounts of forward protrusion relative to the cutter to,thereby, adjust the tilt or angle of presentation of the cutter edge 18.Such tilt is represented by line 32 of Fig. 3.

While I have illustrated and described what I now contemplate to be thebest mode of carrying out my invention, the construction is, of course,subject to modification without departing from the spirit and scope ofthe invention. It is, therefore, not desired to restrict the inventionto the particular form of construction illustrated and described, but tocover all modifications that may fall within the scope of the appendedclaims.

Having thus described the invention, what I claim and desire to besecured by Letters Patent is:
